WILLIAM-W.v SLY, OFSOUTH HAVEN, MICHIGAN.

Leners Patent No. 90,964, dared June s, 1869.

IMPROVEMENT IN' SNAP-EOOKS.

The Schedule referred to in these Letters Patent and making part of thesane.

To all whom t ma/y conce/rn.-

Be it known that I,W1LLLAM W. SLY, of South Haven, iu the county of YanBuren, and State of Michigan, have invented a new and useful Improvementin Snap-Hooks; and I do declare that the following is a true andaccurate description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, and being apart of this specication. f The nature of this invention relates to animprove ment in snap-hooks for connecting togethrlinks, straps, andother parts of harness, and consists in pivoting to a proper hook vavibrating fork through a curved slot l in its shank, in such a mannerthat by the action of a spring under the shank of the fork, the point-ofthe outer prong of said fork will be securely held, when4 the snap isclosed, in a socket in the point of the hook.

In the drawingsv A represents a snap-hook, provided with the usual earsa, and a recess in its base. B is a fork, having twoV prongs, b and b',projecting from'its shank c. d is a curved slot in the shank of thefork, through which passes a screw, e, by means 'of which it is pivotedto.the base of the hook.

D is a spring, yvhich may be coiled, as shown, or

Q-shaped, and so placed in the bottom of the recess,

'hook A, substantially as and for the that one of its ends will exert anoutward pressure on the base of the shank of the fork, causing the endsb. or b to enter a socket, j, in the point of the hookA.

.When the snap is closed, the outer prong 'b ofthe fork is forced by theaction of the spring to enter the socket f, and thus securely retain thelink or cock-eye within the snap.y

To disengage a link from the snap, with the snap in one hand, and thelink in the other, press the link against the base of the fork, whichwill compress the spring-aud permit the fork to moveA the length of itsslot, disengaging the prong b from the socket in the hook, which may bethen opened outwardly, and the link removed.

While I disclaim the use of a coil or other spring in snaps, for movingany part thereof in a straight line,

What Ido claim as my invention,'and desire to secure by Letters Patent,is v The arrangement of the vibrating fork B, provided with the prongs band b and the curved slot d, and operated by spring D, in combinationwith-the recessed purpose above named.' v
